9. PROJECT DESCRIPTION
The project site is the existing Public Beach Access, located in the 4600 block of East Beach Dr., in
Long Beach, NC, in Brunswick County. The property is 250 feet wide and 75 feet deep, however,
beach erosion has reduced the highground property depth to approximately 54 feet. The Town maintains
a pushed up protective berm along this erosion escarpment, in an effort to prevent further loss of
parking area. The property is bordered by East Beach Dr. on the north and the unvegetated beach and
Atlantic Ocean to the south, by private property to the east, and the street end of N.E. 46th St. to the
west, which is part of the Public Beach Access parking lot. There is an existing beach access structure
which includes public bathrooms, open and covered deck, and a walkway to the beach. The Town
installed sandbags on the ocean side of this structure in March 1994 (CAMA General Permit #12426-D),
following several minor storm events. The applicants locate mean high water (MHW) approximately
44 feet waterward of the access structure, however, the slightest lunar, wind, or storm tide will erode
into the man-made protective sand dune.
The Long Term Average Annual Erosion Rate (pg. 2 of 14), lists 2 ft./yr. as the erosion rate for the
project area. The waters of the Atlantic Ocean are classified SB, by the N. C. Division of
Environmental Management. The proposed project is within CAMA's Ocean Hazard and Public Trust
Areas of Environmental Concern, and includes the Ocean Erodible Area, High Hazard Flood Area, and
the Unvegetated Beach Area.
The Town of Long Beach proposes to install a shoreline erosion control and refurbishing structure off-
shore from the above referenced property, in approximately three (3) feet of water at mean low water
(MLW). The structure would be 100 feet long and located approximately 64 feet waterward of MLW.
The applicants have submitted the patent application to provide the structure's specific details. The
structure would consist of triangular units (length not specified) that would be fastened together to reach
the desired length. Each unit would consist of two equilateral triangles, one inside the other, affixed
such that the points of the inside triangle support the straight sides of the outer triangle (See Fig. 3).
The units are constructed from flat sheet components which are assembled to form the triangular
configuration and fastened in place by rivets, screws, or bolts. Individual components would be from
recycled plastic. Since the structure is designed to be placed at a depth, 1 1/2 times the height of the
unit, this site (-3 ft.@ MLW) establishes the unit height at 24 inches. The accompanying sides of the
outer triangle would be 28 inches wide. Multiple units would be attached together to reach the desired
structure length (100 ft.). End caps would close the terminal ends of the completed structure. The
structure would then be floated to the desired location and sunk to the bottom by opening the four
flapper valves in each end cap. Once the structure is in place, it would be anchored to the bottom by
multiple auger screws, with helical flanges, which pass through the center of the structure and help lock
the outer and inner triangles together. The bottom member of the unit has stabilizer fins extruding
downward, one-fourth the height of the unit, or in this case, 6 inches. As the structure is augured into
the bottom, the stabilizer fins would provide additional anchoring. It is unclear in the design
specifications whether or not the augers are metal or molded from recycled plastic. The length of the
auger screws was not provided.
10. ANTICIPATED IMPACTS
The proposed structure would incorporate approximately 233 square feet of public trust area and waters
of the Atlantic Ocean. The proposed submerged structure could pose a hazard to navigation, as well as
swimmers and fisherman. This potential hazard might be lessened, if warning signs were added at both
ends of the structure. Should the structure become dislodged, or break apart due to wave action or
storms, the threat of this hazard would be compounded, as pieces of the structure would be swept to
unmarked locations. Should the structure remain in place and function as proposed, it should raise the
near shore bottom profile approximately 24 inches, as well as the adjacent inter-tidal beach profile.

SHORELINE EROSION CONTROL
AND REFURBISHING MEANS
John G. Mills
Patent Attorney
853H Business Park
P. 0. Box 587
Wake Forest, North Carolina 27588-0587

FIELD OF INVENTION
This invention relates to shore protection and more
particularly to shoreline erosion control and refurbishing means.
BACKGROUND OF INVENTION
Since man first began to settle on the shores of bodies of
water and realized that such shores were eroding, efforts have
been made to either slow down, stop or reverse the process.
Jetties or groins extending out,into the body of water have been
built since ancient times to control the effects of tides and
currents.
With the recent influx of people to coastal areas and the
resulting great increase in the land values in such areas,
erosion control and shoreline refurbishing has become an
increasingly important subject. This is particularly true when
coupled with the environmental issues-raised by the construction
of jetties, groins and sea walls as well as the large scale
pumping of sand in attempts to refurbish and maintain beaches.
BRIEF DESCRIPTION OF INVENTION
After much research and study into the above mentioned
problems, the present invention has been developed to provide not
only and erosion control means for preventing the loss of sand
and soils, but also means that actually causes the shoreline to
- 1 -
I
refurbish itself.
If this is accomplished by providing
triangular-in-cross-section modules which are nestled one inside
the other to form a strong yet relatively lightweight unit.
A plurality of these units can be connected together end to
end to form a line of control and refurbishing means of any
desired length.
Zh abilizing fins are provided on the bottom of the units
have a depth equal to approximately one fourth the heig
janchorin the side of the unit. lso, a plurality of auger type
rovided which pass through the units and
hold the same in place as well as securing the
triangle-in-cross-section-modules relative to each other.
The exterior modules forming the unit are preferably sand
colored so that they readily blend with the surrounding natural
areas.
The string of modules can be assembled on shore, have end
caps placed thereon and floated to the desired use location. At
that point flap valves are opened to allow water and sand to pass
into the interior - of the units -while trapping the same _inside _
once it has entered the means.
The shoreline erosion control and refurbishing means of the
present invention is preferably disposed under water at a depth
of one half the height of the unit. If the waters are tidal,
this depth would be at mean low tide.
- 2 -
The present invention can also be used as an inner sea wall
which will be effective against wind erosion as well as water
erosion at unusually high tides and from storm surges.
DISCUSSION OF PRIOR ART
The following references represent the closest prior art of
which the inventor is aware:
U. S. Patent Number 810,630 to Dwight is a beach making
device that is triangular shaped in cross section. This Patent
is not an equilateral triangle in cross section, however, and
differs substantially from the present invention in that it is
constructed of wood, has a longitudinal opening in one side
thereof and has cross bracing periodically rather than a separate
reinforcing triangle-in-cross-section module for strengthening
the entire outer wall surface of the assembled unit.
Patent Number 3,913,333 to Hubbard, Jr. discloses a means
and apparatus for controlling fluid currents and effectively
preserving and modifying topography subjected thereto. This
Patent discloses hanger pins shown at 26 and land anchors or
pilings 22 to secure the apparatus. This reference does not
disclose nor suggest auger type anchoring means and is entirely
different in structure and material of construction from the
present invention.
Patent Number 4,502,816 to Creter, Jr. et al is considered
of interest in that it discloses a triangular shaped shoreline
breakwater but there the similarity ends. This reference is
manufactured from reinforced concrete and uses its own weight to
- 3 -
-form an artificial reef.
Patent Number 3,653,216 to Stickler, Jr. discloses a method
and apparatus for preventing erosion wherein a plurality of
quonset type huts are connected end to end along a beach. This
reference is constructed of reinforced concrete and does not
otherwise anticipate the. present invention.
Patent Number 4,818,141 to Rauch is noted because a
plurality of units are placed end to end. Again, this is
manufactured from prefabricated concrete rather than plastic and
does not contain the various features included in the present
invention.
Patent Number 4,776,725 to Brade shows an erosion control
apparatus manufactured from reinforced concrete. The pertinency
of this reference is that a plurality of units can be
interconnected as shown clearly in Fig. 1. Beyond this, the
reference is considered of general interest only.
Finally, Patent Number 4,790,685 to Scott et al discloses a
shoreline breakwater for coastal waters with triangular shaped
modules 10 formed from rubber of a medium hard durometer and is
used for forming a beach which, if desired, at low tide can be
shifted inwardly by earth moving equipment. This reference does
-not -teach an equilateral triangle, nor does it include other
internal features of the present invention, nor the method of
placing and anchoring such invention.
OBJECTS OF INVENTION
In view of the above, it is an object of the present
- 4 -
invention to provide a shoreline erosion control and refurbishing
means that includes at least two elongated, equilateral
triangle- in-cross -section modules adapted to have one disposed
within the other and are locked together by auger type anchor
means.
Another object of the present invention is to provide a
shoreline erosion control and refurbishing means constructed from
recycled plastic and colored to blend with the surrounding
natural environment.
Another object of the present invention is to provide a
generally equilateral triangle-in-cross-section shoreline erosion
control and refurbishing means which includes a stabilizing fin
on the lower portion thereof having a depth equal to
approximately one quarter of the height of the sides.
Another object of the present invention is to provide
a_quilateral triangle- in-cross -section shoreline erosion control
and refurbishing units which can be assembled on shore and
floated to their designated use area.
Another object of the present invention is to provide a
shoreline erosion control and refurbishing means including a
plurality of generally equilateral triangle-in-cross-section
units that are shore line assembled, floated to their use
position, and are anchored to the bottom with auger type anchors.
Another object of the present invention is to provide a
plurality of generally equilaterally triangle-in-cross-section
shore line refurbishing units which are disposed on shore to form
an inner sea wall for controlling wind erosion as well as water
erosion during unusually high tides and during storm surges.
- 5 -
Another object of the present invention is to provide
shoreline erosion control and refurbishing means which have flap
valves in the end walls thereof to allow the ingress of water
and sand while preventing the egress thereof.
Other object and advantages of the present invention will
become apparent and obvious from the study of the following
description and the accompanying drawings which are merely
illustrative of such invention.

DETAILED DESCRIPTION OF INVENTION
With further reference to the drawings, the shoreline
erosion control and refurbishing means of the present invention,
indicating generally at 10, includes a plurality of modules
indicated generally at 11 composed of a generally equilateral
- 6 -
triangle-in-cross-section outer module 12 and generally
equilateral triangle-in-cross-section inner module 13.
The two modules 12 and 13 of the present invention are so
constructed that they can be shipped in compact form and can be
assembled prior to use.
To accomplish the above, elongated 600 corner members 14 are
provided. If the modules are constructed from recycled. plastic,
these corner members could be extruded.
The two side walls 15 can likewise either be extruded or
molded and are generally flat, .rectangular members and have
openings either formed or drilled in spaced relationship along
the two longer edges thereof. These members are adapted to
receive corner-to-side securing means 16. These securing means
can either be screws, rivets, bolts or the like. They can also
be formed from either plastic or metal so long as they are
impervious to rust and corrosion.
The bottom member 17 of outer module 12 has a plurality of
vertical stabilizer fins 18 downwardly disposed therefrom.
Strengthening gussets are provided on opposite sides at opposite
ends of each of these fins. There is a gap between the fins to
leave room-for the shaft portion of the auger anchor as will
hereinafter be described in greater detail.
The stabilizing fins 18 and their associated strengthening
gussets 19 can be secured to the exterior bottom member 17 by
means such as gluing or can be integrally molded thereinto.
The inner module 13 is likewise constructed from elongated
corner members 14' and three side members 15' which are connected
by securing means 16'.

Openings 20 are provided in the elongated corner member 14
that joins the two side members 15, this being the upper corner
member when the means of the present invention is in use
position.
A plurality of openings 23 are provided in bottom member_ 17
between the stabilizer fins 18. Each of these openings 23 is in
vertical alignment with one of the openings 20 in upper member
14.
An inner module 13 is adapted to slide into each of the
outer modules 1.2 with one corner oC the triangle-in-cross-section
inner module pointing downwardly as can clearly be seen in Fig.
3.
Spaced openings 24 are provided in the horizontal side of
inner module 13 and in the bottom corner member 14' thereof.
These last mentioned openings are in alignment with paired
openings 20 and 23.
Handle 24 is removably mounted on auger-shaft 21 by securing
means such as pin 25 and can be removed from such shaft. The
shaft can then be passed through aligned bottom opening 23 of the
outer module, the corner opening 25 of the inner module, the side
-opening _24 of the inner module, and the upper opening 20 of the
outer module to effective lock the inner module and outer module
together in the strength bracing configuration, again as shown in
Fig. 3.
Helical plates or flanges are secured by weldment or other
means to the end of each shaft 21 opposite handle 26. When a
shaft 21 is passed through the two modules as described above,
the helical plates will lie adjacent the stabilizing flanges 18
- 8 -
with the handle being disposed adjacent the upper corner member
14. This effectively locks the auger shaft 21 in module
retaining position.
One end of each of the control and refurbishing units 11 has
the corner members projecting outwardly beyond the sides as does
the inner module as can clearly be seen the Fig. 2. The opposite
end of the unit has the corner members and the inner module
recessed an amount equal to the outward projection on the, other
end. Thus it can be seen that a plurality of units can quickly
and readily be slipped together, projections into recesses, and
hold together by means such as unit securing means 29. These
securing means are similar to securing means 16 and 16'.
Once the desired number of units 11 have been secured
together by unit securing means 29, end caps 30 can be mounted to
enclose the open ends of the t-ao end units and can be secured in
place by securing means 31.
Each of the end caps or plates has four openings 34 therein
corresponding to the four tunnel-like longitudinal areas formed
by positioning of the inner module in the outer module as seen in
Fig. 3.
A flap valve 32 is provided on the inside of each of the end
caps or plates 30 juxtapose to each of the four openings. The
purpose of the flap valves is to allow ingress of water and sand
when the shore erosion control and refurbishing means of the
present invention is in use but to prevent egress thereof as will
hereinafter be described in greater detail.
An eyelet-like means 33 is mounted on each of the flap
valves 32 aid is adapted to outwardly project through the
- 9 -
adjacent openings 34 of cap 30.
Locking pins 35 are provided and are adapted to pass through
eyelet 33 of each of the flap valves 32 to lock said valves
closed as shown in solid lines in Fig. 5.
A flexible pull cord 36 is connected to each of the locking
pins 35 so that, once the shoreline erosion control and
refurbishing means of the present invention is placed in its use
position, the locking pins can be removed to allow ingress of
water and sand as will hereinafter be described in greater
detail.
The various parts of each unit 11 is preferably packaged
separately but complete with the possible exception of end caps
30 which will only require two for an entire assemblage of
multiple units. Since all of the parts of each unit will lie
relatively flat when unassembled, they can be placed in
relatively flat, stackable cartons for shipment to the user.
Whenever it is desired to use the means of the present
invention, the number of units needed to span the desired area
are moved to the shoreline adjacent such area along with the
desired number of end cads 30. The outer modules and inner
---- -----modules are -then assembled with -the inner module being placed
inside the outer module. The shafts 21 of the auger anchors 22
are then passed through the aligned openings 23 in the outer
module, openings 25 and 24 of the inner module and, finally out
opening 20 of the outer module. The handle 26 is then placed on
the end of shaft 21 and secured in place by a pin 27.
Once the above is accomplished the modules are locked in
place, one relative to the other. This can clearly be seen in
- in -
Fig 3.
Assembling of the units continues until the desired number
have been put together and joined. The end caps 30 are then
placed on opposite ends of the assemblage of u nits. Tile pins 35
are inserted into the various eyelets 33 of the various flap
valves 32 to effectively seal the assemblage and make the same
relatively water tight.

/ The assemblage 10 can now be moved into the wat,er and
floated out to a depth that is equal to appro ximately one and one
half time s the height of the unit. LE the water_ is tidal the
depth of placement- would preferabLy be Lhe height of the unit
times one and one half at mean low tide.
-C===> Once the desired location has been reached, the pull-
cords 36 are manipulated to remove the locking pins 35 from the
flap valve eyelets 33 in the end caps or plates 30. Once the
locking pins have been pulled as described, water and any sand,
silt or other suspended matter will enter the interior of the
assemblage 10 thus allowing the same to be sunk to the bottom.
Once the assemblage is resting on the bottom 44, the augers
22 with helical flanges 28 can be augered into the bottom by
turning of handles 26 in a -manner similar to the auger anchor
used for guidewires on utility poles. As the augers are pulled
tight, the fins 18 and their associated gussets 19 will be forced
into the bottom of the body of water until flat bottom member 17
lies juxtapose thereto. Thus it can be seen that with the
combination of auger anchors, stabilizer fins, and strengthening
gussets, the assemblage of the present invention can be held
securely in place.
Even after the assemblage of the present invention has been
sunk and secured in place, the flap valves 32 will continue to
open as currents place inward pressure thereon thus allowing
sand, silt and other water born maLer.ials Lo inyr.ess in (.) Lhe
interior of such assemblage but will prevent the egress of the
same since an outward moving current will automatically close
such valves. Over a period of time more and more sand and silt
will build into the interior of the assemblage thus further
weighting the same down and giving it more holding power.
As waves 42 approach the shore.l i.ne and the upwardly sloping
bottom 44, the underlying wave currents 37 will be directed
upwardly by the seaward side walls or members 15 causing the wave
to crest or break. As this occurs, suspended sand will be
deposited adjacent said seaward wall. As this continues to
reoccur, the sand will build up as indicated at 41.
After the wave breaks it moves shoreward as indicated at 38
and then, of course, will reverse and wash back seaward as
indicated at 39. As this runoff approaches the shoreward side of
member 15, it will wash sand back thereagainst as the water goes
over the assemblage 10. As this process continues to repeat
itself, sand will be-moved against and deposited on the-shoreward
side as indicated at 40.
Once the assemblage means 10 of the present invention has
been anchored as described, it will not only prevent -additional
erosion of the shoreline from occurring but will also actually
build up the bottom and refurbish the same.
Once the sand has built up around the first assemblage
enough to refurbish the shoreline, another assemblage can be
11) -
placer seaward thereof and let the refurbishing process repeat
itself .
From the above it can be seen that the present invention
provides a shoreline erosion control and reCur.bishi.ng means that
is environmentally safe, is constructed from recycled material,
is easy to assemble and move to its use location. Also it is
extremely stable once secured to the bottom of the body of water.
The means of the present invention is also highly efficient in
accomplishing the desired results of both controlling erosion and
causing the shoreline to be refurbished.
The terms "upper", "si.de°, "boLLuln" and so forth have baP_n
us.=d herein merely for convenience to describe the present
invention and its parts as oriented in the drawings. It is to be
understood, however, that these terms are in no way limiting to
the invention since such invention may obviously be disposed in
different orientations when in use.
The present invention may, of course,-be carried in other
specific ways than those herein set forth without departing from
the spirit and essential characteristics of such invention. The
present embodiments are, therefore, to be consider=_d in all
respects as illustrative and not restrictive, -and -all changes
coming within the meaning and equivalency range of the appended
claims are intended to be embraced therein.

Enclosed is the application of the Town of Long Beach, represented by Mr.
Jerry Walters, for Department of the Army (DA) authorization and a State
Water Quality Certification to install a plastic, triangular sand trapping
structure on the Atlantic Ocean beachfront, Long Beach, Brunswick County,
North Carolina. Your receipt of this letter verifies your acceptance of a
valid request for certification in accordance with Section 325.2(b)(ii) of our
administrative regulations.
We are considering authorizing the proposed activity pursuant to Section
404 of the Clean Water Act, and we have determined that a water quality
certification is required under the provisions of Section 401 of the same law.
A Department of the Army permit will not be granted until the certification
has been obtained or waived.
In accordance with our administrative regulations, in most cases, 60 days
after receipt of a request for certification is a reasonable time for State
action. Therefore, if you have not acted on the request, or asked for an
extension of time, by June 5, 1995, the District Engineer will deem that
waiver has occurred.
Questions or comments may be addressed to Mr. Michael Hosey, Wilmington
Field Office, Regulatory Branch, telephone [phone].
Sincerely,
e Wrig
